EDWARD W. ROBINSON, OF SAVANNAH, GEORGIA, ASSIGNOR TO INTERNATIONAL BARREL COMPANY, OF SAVANNAH, GEORGIA, A CORPORATION OF GEORGIA BARREL Application filed March 1,

To all whom it mayconcernr Be it known that I, EDWARD W. ROBINSON, a citizen of the UnitedStates, residing in Savannah, Georgia, have invented certain Improvements in Barrels, of which the following is a specification.

One object of my invention is to produce from a straight strip of sheet metal a trans veriely split end hoop for a barrel, keg, cas or the like (hereinafter, for convenience, termed a barrel) and another object is to firmly secure such hoopupon the stave ends and head of the barrel.v These. objects I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in which Figure 1 is a perspective view of the straight strip from which the hoop is to be produced; Fig. 2 is aperspective' view of the same after it has been bent into split ring form; Fig. 3 is a perspective view of after the further bending of the same; Fig. 4 is a sectional view, on a larger scale of the end of a headed barrel with the finished hoop applied thereto; Fig. 5 is an end view of the hooped barrel shown in Fig. 4, and Fig. 6 is a transverse section, one. still larger scale, on the line w-a, Fig. 5.

The blank from which the hoop isto be made is shown in Fig. 1 and consists of a straight strip 1 having flanges 2 and 3 at a The first step in the production from this strip of thefend hoop for the barrel is to bend the same into split ring form, the flange 2 being bent flatwise and the flange 3 ed ewi'se, as 'shown in Fig. 2, the flatwise bendlng of the flange 2 causing nochange in the character of the same other than the change from the straight to the curved form, but the edgewise bending of the flange 3 causin the same to become, wrinkled or corrugated, depth of the corrugations increasing from its point of junction with the flange2to' free edge of the flange because of the the contraction in diameter of the free edge of the flange as the same is bent from the straight to the curved form; The flange 3- is then again bent downwardly at a: and inwandly at 3/ (Fig. 3) sothat .the 'finished hoop presents four members 4, 5, 6 and -7,

4 being adapted to bear against s s Specification of Letters Patent.

being substantially parallel. with one another and projecting downwardly from the member 4: so as to bear, res ectively, against the inner and outer sides 0 the staves at the end of the barrel, and the member 7 projecting inwardly from the member 6 so as to bear-against the head of the barrel, as shown in Fig. 4:. In bendin the flange downward from m to y the wrin es originally formed in that portion of the flange 3 between the line a; and the inner edge of the flange are partially straightened out again, .owing to the increase in the diameter :of this portion ofgthe strip which ist hereby effected, the wrinkling at the line jl being practically to the same extent as at the linea but increasing from the line y to the inner edge of the flange 7. The final bendingof the hoop is preferably effected by means of an appropriate press which also has the effect oi flattening, in a measure, the wrinkles .or corrugations originally !formed in the flange 3 by the bending of the\ same into ring form.

By preference, the split hoop is contracted slightly in applying it to the barrel so that its ends will overlap, as shown in Figs. 4,

My improved end hoop, although applicable to barrels generally having sunken.

wires, the outer flange 5 of the end hoop both in the single and lapped portions of the same being crimped around the outer wire 0 of said end pair of wires, as shown in t and 6. 11 order to prevent loosening of the hoop after it has been applied to the barrel the are secured togather in any suitable way, preferably by driving a staple (1 into the head a through in Fig. 6, and .b Stave through t flange :5gwhere the driving a staple f'into a e lapped portions of the same are crimped around as'also shown in Fig. 6, either of these methods of; fastening may be employed to the exclusion of the other, if desired. A

, The sheet metal of which the end hoop is composed is of practically uniform thickness and strength throughout, there being expanded at and crease in size from the outer to the inner portion of said end bearing flange and are continued throughout the depending flange.
